メンバ	解説
Bottom	オペランドで指定された 'X' が、値の下位 'X' かどうかをテストします。
BottomPercentile	オペランドで指定された 'X' が、値の下位 'X' パーセントかどうかをテストします。
Contains	条件値が比較値を含むかどうかをテストします。
DoesNotContain	Contains の逆。
DoesNotEndWith	EndsWith の逆。
DoesNotMatch	Matchの逆。
DoesNotStartWith	StartsWith の逆。
EndsWith	値が比較値で終わるかどうかをテストします。
Equals	２つの値が等しいかどうかをテストします。
GreaterThan	値が比較値より大きいかどうかをテストします。
GreaterThanOrEqualTo	値が比較値より大きいか、または等しいかどうかをテストします。
In	値が指定した値かどうかを確認します。
LessThan	値が比較値より小さいかどうかをテストします。
LessThanOrEqualTo	値が比較値より小さいか、または等しいかどうかをテストします。
Like	比較値（ワイルドカードを含む文字列）に対して値のワイルドカード比較を実行します。
Match	比較値 (正規表現を含む) に対して値の正規表現比較を実行します。
NotEquals	2 つの値が等しいかどうかをテストします。
NotIn	値が指定した値ではないかどうかを確認します。
NotLike	Like の逆。
StartsWith	値が比較値で始まるかどうかをテストします。
Top	オペランドで指定された 'X' が、値の上位 'X' かどうかをテストします。
TopPercentile	オペランドで指定された 'X' が、値の上位 'X' パーセントかどうかをテストします。

解説

ComparisonCondition　の ComparisonCondition.Operator プロパティの指定に使用します。

        ' Now add the filter. For child field layouts, each individual parent
        ' record's child records can be filtered independently. That is one parent
        ' record's child records can have different filter criteria from another
        ' parent record's child records. This is the default mode of filtering. You
        ' can change it by setting RecordFilterScope property to AllRecords in which
        ' case all child records in the child field layout are affected by the
        ' filter. However depending on the mode, the place where you specify the
        ' filter criteria is different. For the default SiblingDataRecords mode, you
        ' need to specify the filter criteria on RecordFilters property of the child
        ' RecordManager of a parent record. For the AllRecords mode, use the child
        ' FieldLayout's RecordFilters property. Note that the root field layout
        ' doesn't support SiblingDataRecords mode since it doesn't have multiple
        ' record collections and therefore for the root field layout, always use the
        ' field layout's RecordFilters property.
